My Honduran red points bite me when I scrape the algae off their tank because they're always guarding fry. Not too bad cuz they're only like 3" and not made to inflict pain on things, but I'm thankful my freddie and 5.5" male septemfasciata are more afraid of me than I am of them, as I fear what they could do if they did decide to bite me. Obviously not as bad as a gator gar, but would still probably draw blood, and not be fun.
